How can we improve Breeze Server?

Add the Ability to add additional parameters to SaveChanges Call

For retrieving entities you are able to add a WithParameters option that allows the developer to send additional params along with the query. I would like to see the same option with SaveChanges. We have to pass up an authentication token that is required for all call we make to server. Right now it looks like you need to use SaveOptions--but that is not consistent .
